1 Claim. 1

This invention relates to cooling means for internal combustion engines, and in particular means for cooling internal combustion engines by circulating air through jackets around th cylinders of the engine by the vacuum thereof and using the circulated air in the carburetor thereof.

The purpose of this invention is to provide an improved method of cooling internal combustion engines by air so that the use of water is e1iminated.

Various devices, such as fins on the engine cylinders have been used for cooling internal coinbustion engines by air, but it has been found that to use the air heated in cooling the cylinders in the carburetor of the engine increases the efficiency thereof. With this thought in mind this invention contemplates using the suction of the vacuum to draw air from the atmosphere through jackets around the cylinders and through the valve chamber into the carburetor wherein the engine functions as a heat exchanger and the heated air supplies the carburetor.

In the accompanying drawings one complete example of the physical embodiment of the invention is illustrated according to the best mode thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure Within the scope of the appended claim.

In the drawings:

Fig. 1 is a side elevational view of the engine of my invention.

Fig. 2 is a longitudinal vertical sectional view.

Fig. 3 is a fragmentary rear elevational view showing the rear air intake.

Fig. 4 is a sectional plan on line 4-4 of Fig. 1 showing a deflecting baiile in the intake manifold.

Referring now to the drawings wherein I have illustrated the present preferred embodiment of my invention, I employ an engine block 2 formed with crankcase 4, and clutch housing 6. The generator 8 is driven by a belt 9 from crankshaft l and the block is fashioned with head l2 secured by studs l4.

Interior of the block I use cylinders 16 for pistons l8 and the cylinders are spaced forming passages 29.

Forward of the block I fashion an opening 22 communicating with the passages 20 and allowing air to enter the opening 22 and circulate through passages 20.

A housing 24 open at 28 at the front and at 23 at the rear communicates through ports 30 with the passages 20 and coupling 32 is secured to the housing to cover the opening 26.

Pipe 34 secured to the coupling at 36 receives the flexible connection 38 which extends rearwardly to the intake nipple 40 of carburetor 42 secured by studs 44 on intake manifold 48. The exhaust inanifold 48 is provided with a central outlet 50 which is bolted to the lower end of chamber 48 on intake manifold.

The valves, not shown, reciprocate in sleeves 52 located vertically in the housing 24 and it will be apparent that the vacuum pressure of the intake, and pressure of air coming into the opening 22 will force the air into and through the carburetor and into the intake manifold through the section 48.

The intake manifold is formed withdaterally extending branches 5d and 56 which extend to cylinder connections 51 and 58. The manifold is also provided with a centrally disposed cylinder connection 59 and a deflecting baffle E0 is provided in front of section 5 to deflect the incoming mixture into the branches 54 and 56 thereby equalizing the distribution of the mixture.

Under normal operation of internal combustion engines, the vacuum pressure is greater at idling speeds and it will be apparent that as the engine speed increases and vacuum pressure decreases, the air pressure through opening 22 will increase maintaining a stable pressure to and through the carburetor.

No Water is needed to cool this engine as the engine heat in the cylinder walls is absorbed by the air passing therearound and the heated air increases the engine efficiency thereby reducing the heat of operation.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

In an internal combustion engine having an intake manifold, valves, and a carburetor, an engine block having separated cylinders surrounded by jackets providing an air chamber around the cylinders, said chamber having an air intake opening at one end, a valve chamber around the valve stems of the engine having openings providing communicating means with the chamber around the cylinders, said valve chamber having an opening to the atmosphere in one end thereof, and means connecting the opposite end of said valve chamber to the intake manifold of the engine through the carburetor, said intake manifold having a centrally disposed deflecting baflle evenly distributing the gas and air mixture therein.
